A is the initial population
b is the decay coefficient
X is normally the time.
<span>then is the population half of the initial population of A
for half life you will have
</span>
<span>so the equation becomes
</span>
<span><span>The average rate of change formula is basically the slope formula, where you plug in: f(b)-f(a)/b-a. Then plug in the numbers. [f(0)=1,f(3)=7)]. So, 7-1/3-0. 6/3 is 2 so the average rate of change is 2. And that makes sense because the average rate of change is always the slope, and the slope is 2.</span></span>
Answer: statement 2: a square is always a rhombus.
Step-by-step explanation:
A parallelogram does not have all the interior angle as right angle.
Therefore, it does not satisfy property of rectangle.
A square has all sides equal and its diagonals are perpendicular bisector.
Thus, square satisfies all the properties of rhombus .
A rectangle does not have all the sides are equal.
Therefore, it cannot b e a square.
Answer:
5 times shorter
Step-by-step explanation:
The period is the time it takes for one cycle to complete, or in this case, one breath. Since person A is breathing 5 times faster, the time per breath is 5 times shorter.
